A fixed public seating construction includes welded structural steel frame assemblies, each of which includes a standard, a floor mount plate, a seat support or mounting bracket, a back support or mounting bracket, and an arm rest support, all welded together at the manufacturing plant as a single unit. The public seating construction also incorporates relatively rigid plastic shell type seat and back components which will accommodate (on their 'back' or non-use sides) optional inserts of wood, laminate, fabric, etc. Both the back and seat components are comprised of unitized, blow molded shells, filled with foam. In addition, both have mounting assemblies which include steel mounting inserts fixed in place during the blow molding operation, as well as associated support bars which are fastened to the inserts in overlying relationship, prior to shipping. Both the back and seat components have 'drop-in' mounting features, and a free floating hinge is also provided for mounting the seat to the frame.

Public seating chair

A personal office or work chair is provided which includes an open frame construction wherein a seat portion of the chair includes a pair of front springs mounted on either side of the frame, each spring located between frame members extending rearwardly toward the chair seat back portion of the chair, and forwardly to the front edge of the seat portion. In a preferred arrangement, each spring comprises a strip of non-woven fiberglass epoxy resin including forward and rearward substantially planar mounting portions. At the same time, the seat back portion of the chair includes an open frame wherein a pair of laterally spaced frame members are hingedly secured to the corresponding laterally spaced frame members of the seat portion by a hinge bar or rod extending across the frame. One each side of the frame, there is a relatively rigid but somewhat flexible plastic spring fixedly secured between adjacent seat frame and seat back frame members, overlapping the hinged connection between the seat and seat back frame portions. These relatively rigid plastic springs are generally L-shaped and are fixedly riveted to the seat frame members.
